Police estimate 1,000 teenagers crowded inside Monroeville Mall on the day after Christmas, spurred by a buzz on social media about gathering there, and some of them got into brawls.

After a meeting with mall officials on Tuesday, the mayor, police chief and municipal manager of Monroeville said it was an isolated incident and the mall is safe -- and they promise steps are under way to make sure it stays that way.

Monroeville has long had a police mini-station inside the mall. In the past year, it had been displaced by changing demand for retail space. That police outpost will be restored in the new year.

"We're relocating that and getting that put together, and we're going to move forward with that on a little quicker pace than it's been going," said Cole.

They also promise that the response to Friday's night of trouble will include actions by the mall itself.

"The mall management, they have a plan but they did not want to release what their plan is at this time," said Municipal Manager Tim Little. "A plan to reinforce the idea that it's a family-friendly mall."

Natalie Steinberg, of Plum, is one of the shoppers who saw the incident on Friday.

"Everyone was just starting to get kind of loud and obnoxious, and it was kind of scary, to be honest," Steinberg said.

Other shoppers have their own ideas of what they'd want to see to ease their concerns.

"As soon as they start seeing a bunch of those kids showing up again, they should probably nip it in the bud right away," said Cathy Kocher, of Plum.

"I would probably want to know there was more of a police presence instead of just mall security guards -- something like that," said Steinberg.

"Maybe just increase their staff, patrol a little more," said Courtney Tuttle, of Jeannette. "But kids will be kids, I guess."

Authorities said they see no evidence that there were organized plans for trouble on Dec. 26, despite the brawls that broke out.

"These are juveniles we're dealing with. They get on that (social) media stuff and it's hard to tell why they did what they did," said Mayor Greg Erosenko. "But again, it was an isolated incident. I don't anticipate any other issues with that. Monroeville Mall is very safe. You just need to know that. I shop there regularly with my 3-year old grandson and my wife and family."

The police chief says that while some media have described the incident as a flash mob, police are not using that term and they have nothing to indicate that it was organized as a flash mob.

"No, we've not seen anything," Cole said. "This was the, 'Hey, let's get to the mall on Friday evening,' it got out on social media, and many, many people came to the mall because of it."

A police investigation of two separate assaults that happened during the incident continues. One 18-year old has been charged with disorderly conduct. Other suspects involved are juveniles and at least one of them could face charges, according to Cole. Two victims, both under 18, were taken to Forbes Hospital.

Cole said Monroeville has seen a drop in crime and that there had been "zero" robberies and car thefts on mall property in 2014.

Mall management didn't attend Monroeville's news conference Tuesday. A spokeswoman says the mall has several things in the works to address public concerns and will announce them when they're finalized.

"As a private property owner, one of our top priorities is to provide customers, retail partners and employees with a comfortable, convenient, and enjoyable shopping experience. We're confident that the conversation today will lead to positive changes and we look forward to sharing those with you in the coming weeks," mall spokeswoman Stacey Keating said in a prepared statement.

Christine Smatlak, of Indiana County, was in the mall with her daughter, who was celebrating her 14th birthday. Smatlak said a fight happened a few feet away from where they were checking out.

"She was scared. As adults, we were scared," Smatlak said. "You could just hear the yelling, screaming. You could see kids jumping, kicking someone else."

Cole said part of the problem was that local teenagers flocked to the mall Friday because of social media. Teenagers posted on their cellphones that the mall was where they planned to be. When so many juveniles gather in one place without a lot of supervision, Cole said fights are likely to happen.

Smatlak said employees in the store where she was shopping were calling for help.

"It was a very long time before -- I don't even think I saw security. There was other kids helping the kid because he was bleeding," Smatlak said.

Management decided to close the mall shortly before 9 p.m. due to the fights.

"We were actually strategically planning how to get out of the mall, what's the safest way to get out of here, what do we do if something does happen before we get out of here?" Smetlak said.

As one fight ended, another one began to heat up. A second batch of fights caused Monroeville police to request assistance from the Allegheny County, Pitcairn, Trafford, Wilkins Township and Churchill police departments. The Port Authority was notified to send extra buses to get people home.

"It appeared to be no type of a protest, just that there were many juveniles -- and I mean (also in) the age category of 19 or 20 years of age," Cole said.
